The system is designed based on the M/S structure by using access permission control technology which is combined with the validity check of terminal access authentication, forced terminal registration and terminal application environment. Linkage of client program and control end can realize real-time patrols of mobile terminal network behavior. The real-time monitoring of state for the mobile terminal from multi-dimensional can make the terminal always consistent with security strategy to ensure that the mobile police accesses public security intranet safely.
